IMPROVEMENT IN FLIERS FOR SPINNING.

The Schedine referred to in these Letters Patentand making part o the same.

ATo all whom it may concern:

Be it known that we, WLLIAM LA Bimrs'rnn and CHARLES W. IiIeKnn, of Charlestown, in the county et' Middlesex, and in the State ofMassachnsetts, have' reference being had to the accompanying drawings,

and tothe letters of reference marked thereon, makingl a part of this speclieat-ion.

The nature of our invention consists in a tlier for cotton spinning, the legs of which are constructed as herf'binafter describe/.1, and provided with projections, cast with them, to take the place ofthe guide-wire on the old iiier.

In order to enable others skilled in thc art to which our inventionHappertains, to make and use the same, we will now proceed to describe its constructionand loperation, referring to the annexed drawing, which represents a perspective view of our invention.

The general shape or outline of our cotton-spinning flier is the same as those now in use, A being the head, B, the foot, and C C, the parallel legs or nprights.

The legs or nprightsO G are each east in one piece, with a boss or projection, I), at about the centre, and on opposite sides of the ier, which projections are irilled and slotted, as shown, so as to form guides for the thread.

The simple guide-wire on the usual fliers often breaks the thread, and isoften broken itself, by knots but, in this case, the boss is not a wire, but a part of the upright, and, consequently, will notfbe broken 'so easily, nor will it break the thread.

Above the bosses or projections I) D, the legs or nprights C C are oval or elliptical, and below the same they are semicircular, so as to strengthen the ier at the points where the greatest strain is upon it.

Owing tothe great speed with which iiers are generally rnn, the uprights are very often thrown out of their normal position, or bent, 'thus shortening vthe iiier. This is entirely obviated by making them in the form above described, as the air will not give so much resistance, the legs or uprights, so to say, cutting the air. For this reason, our liier can be run at about one-third more speed than usual. lt is cheaper, and will make better work.

vThe flier thns constructed maybe cast of malleable iron, or forged of either steel or iron, o1" cast of any metal, hardened or case-hardened.

Having thus fully described 'oni' invention,

What we claim as new, and desire to secure by Letters Patent, is-

'lhe combination ofthe head A, foot B, uprights C* O, and bosses or' projections D D, when said projections are formed in one piece with the nprights, and saiduprights are oval above, and semicircular below saidprojections, substantiallyv as'and for the purposes herein set forth.

In testimony that we claim the foregoing, we have hereunto set our hands andv seals, this 6th day of September, 1869.
